328 is the answer to your mathematics question young one.
THEOREM:
- Alternate interior angle —: When two lines are parallel (||) then the Same-side interior angles always add up to 180°.
ANSWER:
By alternate interior angle theorem,
- ∠3 + 90° = 180°
- ∠3 = 180° – 90°
- ∠3 = 90°
Hence, the measure of angle(∠) 3 is 90°.
It's going to be 10 because it's closer to ten
